New submission from Jan Kaliszewski <z...@chopin.edu.pl>: del list_instance([start : stop : very_big_step]) causes segfaults...
The boundary values seem to be: * start -- near length of the list * stop -- near (-length) of the list * very_big_step -- near sys.maxint Let examples speak... >>> from sys import maxint >>> del range(10)[::maxint] Segmentation fault >>> from sys import maxint >>> del range(10)[13::maxint] >>> del range(10)[12::maxint] >>> del range(10)[11::maxint] >>> del range(10)[10::maxint] >>> del range(10)[9::maxint] Segmentation fault >>> from sys import maxint >>> del range(10)[:-13:maxint] >>> del range(10)[:-12:maxint] >>> del range(10)[:-11:maxint] >>> del range(10)[:-10:maxint] >>> del range(10)[:-9:maxint] Segmentation fault >>> from sys import maxint >>> del range(10)[-8:8:maxint-5] >>> del range(10)[-8:8:maxint-4] >>> del range(10)[-8:8:maxint-3] >>> del range(10)[-8:8:maxint-2] Segmentation fault System Info: * Python 2.5.4 (r254:67916, Apr 4 2009, 17:55:16) * [GCC 4.3.3] on linux2 * sys.maxint == 2147483647, sys.byteorder == 'little' * Processor: Pentium 4 * libc version: 2.9 (2.9-4ubuntu6) ---------- components: Interpreter Core messages: 98348 nosy: zuo severity: normal status: open title: segfault when deleting from a list using slice with very big `step' value type: crash versions: Python 2.5 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue7788> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
